Bikesters are quite useful - they are my preferred over-wear in the Winter 6 months of the year. This doesn't explain why they are so hard to come by.
When I first bought some, a few years ago, they were £22 for Two Pairs on a Wiggle special.
Now you can just about get one pair for that if you dig about on the interweb. What's going on? Am I the only person who uses them? Surely not!
